Perfect your flying skills and pass your check ride.
From From FAA.gov:
"The pilot administering the check is entrusted with the responsibility of making sure you meet the aeronautical knowledge and aeronautical skill standards established in the United States for the certificate you are seeking to obtain. When the DPE signs your temporary pilot certificate, he or she is attesting that you are competent not only to carry yourself aloft — something you’ve already been doing during solo practice — but also to carry passengers."

From Flying Magazine:
"Every time you train for a new pilot rating you’re faced with a check ride — an event that can cause the blood pressure to rise even in the best of pilots. After being grilled for hours about your knowledge pertaining to the rating you’re attempting to achieve, you’re expected to perform precision maneuvers under the watchful eye of an experienced pilot examiner. The only way you will pass is by studying the material and practicing the maneuvers, but there are a few additional things you can do to reduce your stress level and increase your chances of passing your test on the first try."
